Power Supply Units (PSU's) are the beating hearts of electronic devices. Buying a cheap power supply is a sure ticket to frying any device.
As a professional in the electronic sales and purchases I have seen far too many times clueless people buying a $1000 PC with a $20 PSU, only to see it burn months later at the first voltage drop.
They matter not only for PC's! Cheap devices purchased from China (websites e.g. 1688.com) come equipped with TERRIBLE power supplies, barely working, minimum cost - these not just break but START FIRES and MAY EXPLODE!
Buy your electronics from reliable stores (bonus points - if MADE IN THE US OF A) and always check for a certified power supply and/or (rechargable) batteries.
First of all, check the power supply. You can see if it looks burnt, but most electronic failures won't be noticed by a layman. Is your PSU blacklisted? If so, case closed. Next time you'll build a better PC.
IF YOUR PSU IS WHITELISTED ----- only then you can email me at email@example.com, I can try to help for $40 + $20/hour - include pictures of the OPEN PC case with the PSU labels visible (mind I don't download emails over 2MB so split it if need be). I work 9-5 Sun-Thu (ET).
